maim. The gold-eye certainly occurs in the Ohio basin. It is, how- 

 \<i\ possible that the Am phiodon alosoides,\\\\\\ other nominal species 

 of Rafinesque, is the common moon-eve, Hiodon tergisus. 



The original accounl of Rafinesque (Journal tie Physique, vol. 88, 

 page I'-'l, 1819, now almost inaccessible) is as follows, as transcribed 

 for us by Mr. Henry \V. Fowler:

In the Ichthyologia Ohiensis, 1820, page 42, the subgenus Amphio- 

 don, based on the Hyodon alosoides, which he now calls Hyodon 

 ampJiiodon, is thus characterized : "Body lanceolate, lower jaw longer, 

 dorsal beginning opposite base of the anal fin. The name means 

 toothed all over." 



This Hyodon amphiodon is stud to have the diameter one-fourth 

 the total length : jaws with large conical teeth, similar to those on the 

 tongue; eyes round and black; iris silvery gilt: dorsal rays 10; anal 34. 



In the second subgenus, Glossodon, based on ' ' Hyodon vematis" 

 (= Hiodon tergisus), the following characters are given: ''Body lanceo- 

 late; jaws equal, with small teeth, dorsal fin opposite the vent, nearly 

 medial, beginning behind the abdominal fins. The name means 



toothed tongue." 



In this species, the dorsal rays are 13, the anal 28; the falcation of 

 the fin indicates t he male. 



In the third subgenus, Clodalus (Hyodon clodalus)) we have the 

 "body oblong, irregular or somewhat rhomboidal. Jaws nearly 

 equal, the lower one somewhal longer and with small teeth. Dorsal 

 (in beginning before the base of the anal fin." In //. clodalus (= Hio- 

 don tergisus LeSueur) the dorsal rays are If), the anal 30. 



In support of the theory thai the Amph'wdon alosoides was the 



n Q-eye and not the gold-eye, we have these phrases; "Caivne ven- 



t r.-de obi use, pen visible." " Nageoires dorsales au-dessus de I 'anus." 



On tl ther hand, in favor of the identity of Amphiodon alosoides 



with the gold-eye, uc have the backward position of the dorsal 

 ah hough it is still farther back in the gold-eye), the presence of 

 ventral carina, however little visible in comparison with the river 

 herring, and especially t he numbers of fin rays, I). io, A. 34, indicating 

 a very long anal and a short dorsal, both characteristics of the gold- 

 eye. On the whole we have little doubt that Kaiinesque had the
